The Belgium international was among the scorers as Unai Emery’s men maintained their impressive home for this season.
Speaking to club’s website, the midfielder assessed the result against the Cherries at Villa Park.
“Everyone’s delighted, it was our biggest victory of the season,” he said.
“Four goals, four different goal scorers – it doesn’t get any better than that.”
“With the ball, we’ve been very proud of how we played out from the back.
“Sometimes I know it can be annoying for the fans but it’s the way we play and it’s what got us to here.
“We need to continue doing that. I think that we beat them at their own game. They’re a very intense team, but today in the duels we were really aggressive. We were spot on.”
